CargoCap is a concept for an underground freight transportation system. It is based on autonomous freight cars, called capsules, travelling through a pipeline network. This thesis studies the energy consumption of the capsules during driving operation.
Special focus lies on the aerodynamic drag, which, due to the operation inside a pipeline network, contributes a substantial portion of the capsules' driving resistance. A CargoCap-specific aerodynamic model describes the capsules as pumps, inducing a
fluid flow in the pipeline network and working against the flow resistances. To account for the influence of e.g. the shape of the capsules, the aerodnamic model uses parameters deduced from CFD studies. Scale model experiments are utilized to validate
the model and the parameter values. The energetic simulation points out options for the aerodynamic optimization of CargoCap by means of the design of the capsule-pipeline-system and the organization of driving operation.
